Hi,
I am using RadGridView with filter set to 'filterrow' (Version 2014.2.729.40). I have a couple of columns and not all columns are visible at the same time. It requires scrolling from left to right to access the rightmost column.
If I insert a filter value into the filter editor of any column (in fact it doesn't matter which one it is), this value is cleared out of the filter editor if this filter editor is scrolled out of the visible part of the window. This does not happen, if I apply that filter via the filter-funnel.
But if I only type a few characters into the filter editor, that value has disappeard after the filter editor reappears in the visible part of the window.
Can You tell me why those inputs are deleted?
I recognized, that the FieldFilterEditorCreated-Event is also called every time a filter editor leaves the visible part of the window. Why?
Regards Heiko

Hello Heiko,
As it turns out I am not able to reproduce the issue. You can refer to the attched test project.
Would you please check it and let me know how is your setup different than mine?

Hi,
please start the 'RadGridView_WPF_AR_6' project, which You attached in Your previous post:
1) please add the width property for the GridViewDataColumns
Width="200" for the 'Name' Column and Width="400" for 'Established' and 'StadiumCapacity'
2) start the project
3) enter a value into the filter row for 'Established' but do not use the funnel to apply the filter
4) scroll slowly to the right => if the column 'Established' reaches the left end of the visible part of the GridView the value You put into the filter for that column disappears and is lost
That is the same that happens in my project and I would like to keep the input because I do not use the funnel to apply filters. I do it in code behind after the filter row lost focus.

Hi Heiko,
Thank you for providing those additional instructions. I was indeed able to reproduce the issue and found the reason for it - it is since RadGridView is a virtualized control and its elements are reused as they are brought in and out the view area during scrolling. You can also check our online documentation explaining how the UI virtualization works.
In order to have the text kept while you do not have any filtering applied, you should disable the column virtualization:

EnableColumnVirtualization="False"Let me know how this works for you.
